What is Epitalon and what is Thymosin Alpha-1?
Epitalon is classified as Synthetic tetrapeptide; Thymosin Alpha-1 as Synthetic 28-amino-acid thymic peptide. Both profiles below cover scientific identity only — what the molecule is and which laboratory models it appears in. Verve supplies both strictly as in-vitro reference materials, and neither profile describes human or veterinary use.
Epitalon
Synthetic tetrapeptide
Epitalon is a synthetic tetrapeptide with the sequence alanyl-glutamyl-aspartyl-glycine (Ala-Glu-Asp-Gly), developed as a short synthetic analog of a peptide fraction isolated from the pineal gland. It is a small, water-soluble peptide and one of the most frequently cited reference compounds in pineal-peptide and cellular-aging research literature.

Synthetic 28-amino-acid thymic peptide
Thymosin Alpha-1 is a 28-amino-acid peptide corresponding to a sequence originally characterized in thymic tissue extracts, where it was identified as part of the prothymosin alpha precursor. Verve supplies it as a high-purity synthetic research compound for the laboratory study of peptide-mediated immunological signaling.
